THE FUEL SYSTEM
The hose/regulator assembly attaches to
the propane gas supply. The propane gas
moves through the automatic control valve
and out the nozzle.
THE AIR SYSTEM
The motor turns the fan. The fan pushes
air into and around the combustion
chamber. This air is heated and provides a
stream of clean, hot air.

Propane Supply
Propane gas and propane tank(s) must be
provided by the customer.
Use this heater only with a propane vapor
withdrawal supply system. See Chapter 5
of the Standard for Storage and Handling
of Liquefied Petroleum Gas, ANSI/NFPA 58.
Your local library or fire department will
have this booklet.
The amount of propane gas ready for use
from propane tanks varies. Two factors
decide this amount:
1. The amount of propane gas in tank(s)
2. The temperature of tank(s)
The chart below shows the number of 100
pound tanks needed to run this heater.
Less gas is vaporized at lower tempera-
tures. You may need two or more 100
pound tanks or one larger tank in colder
weather. Your local propane gas dealer will
help you select the proper supply system.
The minimum surrounding air temperature
rating for each heater is -20°F (-29°C).
